NSSL WRF 4 km grid initialized 00 UTC Dec 13 2017

36 h Total Precipitation (mm) (OUN zoom)

Daily, real-time runs of the Weather Research and Forecasting (WRF)
model are generated using 256 processors on the Jet HPC cluster
(Raytheon/Aspen Systems) in Boulder, CO.

The WRF model (v3.4.1) configuration includes:

MYJ BL/turbulence parameterization

WSM6 microphysics

RRTM longwave radiation

Dudhia shortwave radiation

Noah land-surface model

Positive definite advection of moisture

4 km grid length (1200x800)

35 vertical levels

Time step 24s

Initial and boundary conditions are obtained from interpolation of the
routinely available 40km NAM Model fields obtained from EMC/NCEP, using the
WRF Preprocessing System (WPS). Initialization time is 00 UTC and forecast
length is 36 h.
